INSTRUCTIONS FOR THE CORRECT USE OF THE LOADER VALVE
DUPLO SPRAY VRP 83
KEY:
1. Regulator knob
2. Pressure release lever
3. Discharge connection (by-pass);
4. Use function taps
a) Before starting up turn the lever anti-clockwise (or push it up) to the discharge position
(by-pass).
WARNING! IT IS ESSENTIAL TO COMPLY WITH THIS RULE OTHERWISE
THE GUARANTEE ON THE PUMP IS INVALIDATED.
b) Turn the regulator knob anti-clockwise to reduce the pressure to "0" bars. This is
strongly advised for the initial phase.
c) Only start the pump when the valve is in the "by-pass" position. Leave it running for at
least two minutes and in any case until the air has been completely evacuated from the
hydraulic circuit.
